Doesn't work on Travis yet, because there's no singularity release for xenial. Does anyone remember a specific reason to run that old an Ubuntu, @datalad/developers ?

[yarikoptic]

xenial??? that is nd16.04 , EOLed in April 2021... we can't be using that!... WTF in https://app.travis-ci.com/github/datalad/datalad-container/jobs/590789811 says distribution: debian/stretch/sid and there is no error in installing singularity, only error in finding it or smth like that

 E               FileNotFoundError: [Errno 2] No such file or directory: 'singularity': 'singularity'

? didn't check in further detail

[bpoldrack]

re xenial, @yarikoptic:
See https://app.travis-ci.com/github/datalad/datalad-container/jobs/590789811#L9
According to https://docs.travis-ci.com/user/reference/linux/, xenial is still default on Travis.

That's why the construction of the URL to get the singularity release from, uses xenial (and gets a 404)

And the error with installing singularity is here:
https://app.travis-ci.com/github/datalad/datalad-container/jobs/590789811#L751

Re distribution: debian/stretch/sid reported by datalad wtf:

Could that be neurodebian being at fault here?

When switching to jammy singularity installs fine.

However, now we get a new failure:

$ python setup.py build
Traceback (most recent call last):

ModuleNotFoundError: No module named 'setuptools.command.build'

That's confusing me, though, since it's supposed to be python 3.7 all along. So, what changed here? Also: Do we even need to run setup.py build?

[yarikoptic]

yeah -- let's try without testing that. pushed

[yarikoptic]

Could that be neurodebian being at fault here?

not sure how neurodebian could be at fault... if anything it is the python package at fault we are using in datalad wtf to figure out distribution.

[bpoldrack]

Alright, all green, let's go.
